# Does it work on localhost?

 * I’m testing it on localhost, before launching my website live. I’m running Apache
   +php8.2, on windows 11. The APCu is enabled as it shows in php info, and it has
   these settings in the php.ini:
 *     ```wp-block-code
       [apcu]extension="C:\xampp\php\ext\php_apcu.dll"apc.enable=1apc.shm_size=32Mapc.ttl=7200apc.enable_cli=1apc.serializer=php
       ```
   
 * The APCu shows in the WordPress > Tools > Health also, however the plugin itself
   doesn’t seem to find it. It states “APCu extension is NOT installed/enabled.”
 * I’ve tried changing the browser, cleaning the cache etc, the last thing I wonder
   is whether or not the plugin works on localhost. Any ideas?
 * Thank you

 * It works on localhost and also under windows.
   where in site health do you see
   APC info?can you send a screenshot?

 * What happens if you run this code:
 *     ```wp-block-code
       <pre><?phpprint_r(apcu_cache_info()['mem_size']??'');
       ```

 * When I run the code I get a 0
 * I meant the /wp-admin/site-health.php. I can’t upload images here, but this is
   from the WP health page:
 *     ```wp-block-code
       You should use a persistent object cachePerformanceA persistent object cache makes your site’s database more efficient, resulting in faster load times because WordPress can retrieve your site’s content and settings much more quickly.Your hosting provider can tell you if a persistent object cache can be enabled on your site. Your host appears to support the following object caching services: APCu.
       ```
   
 * And this from my php info
 *     ```wp-block-code
       apcuAPCu Support	EnabledVersion	5.1.24APCu Debugging	DisabledMMAP Support	DisabledSerialization Support	phpBuild Date	Nov 29 2024 01:59:27
       ```
   
 * And from /wp-admin/plugins.php
 *     ```wp-block-code
       atec Cache APCu | Deactivate | APCu extension required!
       ```
   
 * and finally on the plugin’s page
 *     ```wp-block-code
       APCu Object Cache APCu extension is NOT installed/enabled.The object cache is the main feature of the plugin and will speed up your site
       ```

 * Please try to
   `#apc.serializer=php`it might also be useful to in php_apcu_bc.
   dll for APCu with backward APC compatibility

 * Hi,
 * Thanks for your support. I’ve just noticed that it is working fine with my other
   localhost sites, so it must be something with my particular WP installation. 
   I’ll figure it out myself. For now, I can confirm that it works for localhost.
 * Regards
